Description

The PTC heater of air conditioner

Technical field

The utility model belongs to electric heater technical field, is specifically related to a kind of PTC heater of air conditioner.

Background technology

Aforesaid PTC heater also claims ptc heater or PTC heater, and PTC is English abbreviation (English full name is: PositiveTemperatureCoefficient).Ptc heater is made up of following three parts: one is PTC heater body, and this PTC heater body also claims PTC radiator body; Two is tailstock; Three is electrical connection seat.One end and the tailstock of PTC heater body are fixed, the other end is fixed with electrical connection seat, and PTC heater body comprises aluminum pipe, be positioned at the side of the length direction of aluminum pipe or corresponding both side surface and in undulatory radiating aluminium sheet be contained in the intraluminal PTC heat generating core of aluminium of aluminum pipe, wherein, PTC heat generating core comprise plural number piece neat arrangement and corresponding both sides surface with vacuum sputtering coating mode or with other similar mode be combined with electrode layer PTC thermistor (ceramic positive temperature coefficient thermistor) and be arranged on PTC thermistor both sides (also claim to be electrically connected bar with each one piece of electrode slice of electrode electrical contact, as follows).

The PTC heater of said structure form is widely used in air-conditioning particularly wall-hanging (also claiming wall-hanging) air conditioner or similar device, and be no lack of in disclosed Chinese patent literature and be seen in, slightly with " the PTC heater external member " as CN2640002Y recommendation that exemplify, " composite type PTC heater " that CN2753090Y provides, " a kind of heat-conducting aluminium pipe of PTC heater and PTC heater " that CN201499328U introduces, " the two assembly PTC electro-heat equipment of air conditioner " of CN102695306B bulletin, " PTC heater " that CN201499318U disclosed " PTC electro-heat equipment for air conditioner " and CN2392334Y discloses, etc..

In prior art, the PTC heater comprising above mentioned patent formula is all with single or claims the form of single group to be configured on the indoor set of air conditioner, but along with air conditioner power and indoor set inner space change and consider alternative in use procedure, safeguard time the factor such as economy, the economies of resource and the adaptability of apartment size, in the indoor set of air conditioner, configure that two or more PTC heaters can yet be regarded as is an original mentality of designing.Because, for two PTC heaters, user can by the operation of controller according to selecting one or two PTC heater work, and air conditioner still can be made in running order when arbitrary PTC heater fault in two PTC heaters.

But, only namely configure two or more PTC heaters with simple quantity stacked system to air conditioner in the mode copied and can produce following technical problem: because if tailstock and the electrical connection quantity of seat and the quantity of PTC heater body are kept the relation of following in sb's footsteps, specifically, when existence two PTC heater bodies, if use two tailstocks and two electrical connection seats, following technical problem can be produced so undoubtedly: one, because component number is multiplied, be thus unfavorable for manufacturing and assembling; Its two, due to component number object increase, thus can suffer the restriction of the confined space in indoor set, even produce with other parts and interfere; Its three, be unfavorable for economizing on resources and be unfavorable for embodying economy.Certainly, shared for a two or more PTC heater bodies tailstock and an electrical connection seat can be solved this technical problem.

" PTC heater " (this patent is proposed by the applicant) that invention Authorization Notice No. CN104053255A releases meets the requirement of two or more PTC heater bodies being share a tailstock and an electrical connection seat, thus compensate for aforementioned technical problem.But still there are following 4 shortcoming in this CN104053255A: one, although the electrical connection seat that the tailstock due to tailstock inserts chamber and electrical connection seat inserts the supporting role that left end to PTC heater and right-hand member can be played in chamber, but enter into tailstock to insert chamber and electrical connection seat and insert the left end of the PTC heater body in chamber and each a bit of of right-hand member and be in fact and confiscated state by tailstock and electrical connection seat, thus the effective length played a role of PTC heater body is because respectively having been confiscated a part by tailstock and electrical connection seat and be affected.Especially, tailstock is inserted the degree of depth that chamber and electrical connection seat insert chamber and is all about 1-2 ㎝, thus PTC heater body has been confiscated the length of 2-4 ㎝ jointly by tailstock and electrical connection seat, they are two years old, due to when air conditioner is in running order, PTC heater body is inserted into tailstock and inserts chamber and electrical connection seat and insert part in chamber and can insert to tailstock the chamber wall that chamber and electrical connection seat insert chamber and produce baking situation, thus easily undermine the useful life of tailstock and electrical connection seat, such as, make tailstock and electrical connection seat premature aging, cracking and distortion, they are three years old, due to PTC heater body, tailstock and the volume size of electrical connection seat are the designs submitting to air conditioner, and the installing space of air conditioner production firm when designing to the associated components in air conditioner, spacing between the arrangement of position and related functioning components etc. is often calculated carefully and budget strictly the degree must used to very little gap, thus had too many difficulties to cope with in the space of PTC heater, again because the thermostat being used for arranging thermostat is inserted chamber by this patent, for arranging the fuse embedding slot of fuse and being all arranged in the top of electrical connection seat for the rule pin etc. spacing to circuit, thus the highly significant of electrical connection seat is made to increase, subject to the interference of the confined space in air conditioner when being mounted to air conditioner and increase installation difficulty, even there will be the situation suffering air conditioner refusal, they are four years old, due to aforementioned thermostat is inserted chamber, fuse caulking groove etc. is implemented in the top of electrical connection seat, thus protect to make electrical connection flap (patent claim electrical connection seat guard shield) effectively cover thermostat and fuse etc. and electrical connection flap has been designed to sleeve-like structure, so the structure making electrical connection recognize on the one hand is tending towards complicated, add the material consumption for making electrical connection flap on the other hand, improve electrical connection flap on the one hand and be electrically connected seat installation difficulty and affect installation effectiveness again, such as need by means of securing member, the side of electrical connection flap with electrical connection seat to be fixed.

For above-mentioned prior art, still have necessity of improvement then, the applicant has done further design for this reason, and technical scheme described below produces under this background.
